These fatality rates have not been adjusted to account for
double counting across modes because the detailed fatality data needed to do
so were not available at the time this report was prepared. Double counting is of particular concern
across rail and highway modes due to highway-rail grade-crossings fatalities
and across highway and transit due to transit bus fatalities. The Bureau of Transportation Statistics
estimates that the double counting inflates the total fatality rate by about
0.1 fatality per 100,000 residents.
Air and waterborne data are preliminary.
